Moving Boat From Brackish Water To Freshwater

[LuvBoating]

Making plans on moving, us and boat, from Jacksonville, FL to northern Colorado (Front Range) or southeastern Wyoming. Was told by our Mercruiser mechanic that we'd need to change the anodes and prop before using on freshwater lakes.
Is this true and is there anything else we would need to do before putting boat into a freshwater lake?

BTW, boat is a 1992 20' Celebrity Cuddy Cabin w/5.7L (350) I/O w/191 hours on newer long block

Magnesium anodes in freshwater.

Probably need to tweek carb(s)/adjust timing and possibly a prop swap to compensate for the change in altitude

Is it in a slip now? From recent posts, just wondering if there will be a lot of cleanup needed on the bottom and the drive to start out fresh in the new environment.

You will need to have the boat incredibly clean of anything that was once living, so get the pressure washer out if it has been wet-slipped.

Also, looks like Colorado requires inspection/certification if the boat has been in water outside the state.

For the last three years, the boat has been in dry storage. Not a full dry storage, but racks with a roof and end supports. During all the so-called "Florida winters" we've had a deck cover and full cover on it.......both when it was on a trailer and on a rack in dry storage now. IOW, the bottom, bow and stern look brand new, like it would be a 2018 boat.

We are both "sticklers" about keeping the boat clean. Every time we've come back from on the St Johns River, we put the muffs on the outdrive, start the engine and run fresh water thru it. Since owning the boat, have never missed a single time doing this. Except for a few small soft spots on the main deck, the boat is in excellent shape. Last Fall, filled the gas tank with non-ethanol gas from the dock of dry storage, changed the oil and put on new gas filter. Has a dual-battery hookup with two NAPA Starting Batteries. In mid 2016, had the carb replaced with new fully rebuilt one, part of stern redone (new fiberglass) and inside of part of outdrive replaced. Have had other things done to engine and deck in cuddy redone.
Yes, cost us, but boats cost, just like any other recreational item.

I have Aluminium anodes on the drive. Apparently good for fresh water and brackish. You may already have them. But there is no doubt that nothing beats zinc for SW and magnesium for fresh water exclusively.
My boat isn’t antifouled and is in fresh water on Loch Lomond. I have to pull it out a good few times a season to clean the bottom of horrible growth, slime and iron based staining. Oxalic acid is the key.
